WOW IS RIGHT! That era Rock Ola mech and MPU are super reliable. Dual amps too. Nice score.

The Seeburg Microlog jukes were excellent machines. Not only did they perform well but in my opinion they had the best sound of any brand. I’m not an engineer but I think this had something to do with how seeburg placed transformers between the output transistors and the speaker taps. The amp could not be shorted. Well, it could but it would simply shut down until the short was removed and then the sound would resume. I loved that about Seeburg. Do that with just about any other amp and you have a blown amp. The real beauty of this design is in the sound. Seeburgs had a comparatively rich sound reminiscent of tube amps. I’m guessing that this is a result of the transformers in the circuit but they sure did sound good. Unfortunately, Seeburg removed the part numbers from most transistors and replaced them with a unique 6 digit Seeburg part number. When my dad left the local Seeburg distributor in the late ‘70’s he obtained a transistor cross reference list. If anyone needs it I could look for it. Most of the transistors in a ‘70’s era amp are of the 2N2222 variety which had a plastic body. Replace them with the 2N2222A with the metal body and the performance goes off the chart.
Quoted from schudel5:Just picked this up. Records work great...CDs skip but it'll be fun to dig into.

It's likely that the CD laser reader is going bad when it begins to sound like a record thats skipping. I'm only familiar with NSM and Rock-ola, which both used the Phillips Industrial CDM line of laser players. If the problem continues you can have the player rebuilt. There are a number of companies that provide this service. Here's one: https://videogame911.com/philips-cd-pro-2-laser-repair/
EDIT: Sorry, after looking at that again, it's a combo which didn't use an industrial laser player.
AMI wall mount jukebox. Removed from a location years ago when they upgraded to a Touchtunes jukebox. Was working at the time. Condition is fair. Only someone jimmied the lock to open it and caused some damage around the hole. Cash box door and bracket are missing(naturally!).
Free to anyone who wants it. Can bring to Allentown for Friday pickup. Can also provide an NSM wall bracket and knobs if someone wanted to mount it the NSM way.

Adoption Pending.
Find the black box which controls the credit settings. It’s about 1 1/2”W X 8” square. On the end is a circuit board held in by two cap screws. Take out those screws and pull out the board. Removing the board (1 1/14” X 5”) will set it to free play. Now attempt to select a song. If it selects, ok. If it doesn’t select, repeatedly and rapidly press the 1 and 2 buttons to see if you can get it to accept one of the numbers. There’s a switch on the side of the keypad. Clean the contacts by running a title strip or a coin wrapper through it. Don’t attempt to adjust it yet. Repeat trying to select a record.
If no selection occurs then find the control center. There will be a single wire that plugs into it via a mini RCA type connector. Get a D cell battery. Pull the cable, hold the positive end of the battery against the case of the control center then take the cable and touch the back (negative) end of the battery. Then plug the cable back in and then start the mech. If done correctly, this will charge the tormat unit and the mech (if working correctly) will pick up every record in the machine both front and back. This will tell you 1) if the mech is working correctly (if not, the problem is mechanical and 2) if so, if the problem is electronic. It’s been thirty some years since I’ve worked on these so I’ll have to really think about this.
ToucanF16 Ha! My dad worked for Atlas Music in Pittsburgh which was the local Seeburg distributor and exclusively operated Seeburgs for years until he retired. I went on a LOT of service calls with him. FWIW-I have a large number of these Seeburgs that he stuffed into a container back in the 80’s and which have suffered from the weather and are likely just parts machines. They range form the SPS bandshell models, STD models up through the SMC-2. So if anyone needs any parts let me know. There is one Matador in there like Bam_Man’s and I always planned on keeping that one because I consider it the best looking model of that era.
